Brian H inspired me to attempt a wigwag engine build so here is what I have so far.

The easy part, the base and column.



Sourced a piece of 3" round from @johnnielsen for the fly wheel. Thanks John!




Aluminum cylinder made from square stock with the cylinder bore offset on the body. Learned a lot doing that operation.

Turning the piston

Manual threading the connecting rod. Not fun.

Crank connection, connecting rod and piston AND a failed connecting rod.

The build so far. The piston to cylinder fit actually exhibits compression so that's encouraging.
I neglected to record making the crank🙁
